Firebug start button in Firefox toolbar

Since Firefox 4 eliminated the status bar and introduced a new add-on bar Firebug needs to adapt to the case where the old status bar icon isn’t visible.

As depicted on the screenshot above, there is a toolbar button having exactly the same functionality as the old status bar icon. For instance, clicking on it opens/hides Firebug, the same context menu is available, number of errors (if any) is displayed, it’s gray if Firebug is not active, etc.

This toolbar button has been available in the Customize Toolbar dialog for some time, but it’s now refactored and also inserted into the toolbar automatically (just after installation). If you prefer the good old status bar icon, you can remove the button (using Customize Toolbar dialog) and open the add-on bar.

Thanks to all who helped to solve this issue and provided valuable input when we asked for it!

getfirebug.com has new Firebug 1.6.2 that fixes couple of problems (issue 3880 and issue 3933). We are being conservative and fixing only the most important & low risk problems since this release is planned to be the last one for the 1.6 branch.

Firebug 1.7 is close to beta phase and we want to focus our effort on it.
